Coding Style

[Blog Map]  [Table of Contents]  [Next Topic]

Sometimes when using the method syntax for a complicated query, you dot into method after method after method, as you can see in the example in the previous topic.  These lines can get very long, and a little hard to read.  One approach that I’ve used to good effect is to use a coding style where I line up the dots vertically.  When coded with this style, the query is written like this:

This blog is inactive.
New blog: EricWhite.com/blog

Blog TOCvar paragraphs =
mainPartDoc.Root
.Element(w + "body")
.Descendants(w + "p")
.Select(p =>
new
{
ParagraphNode = p,
Style = (string)p.Elements(w + "pPr")
.Elements(w + "pStyle")
.Attributes(w + "val")
.FirstOrDefault()
}
);

The restyling of the query using a query expression looks like this:

var paragraphs =
from p in mainPartDoc.Root
.Element(w + "body")
.Descendants(w + "p")
let style = (string)p.Elements(w + "pPr")
.Elements(w + "pStyle")
.Attributes(w + "val")
.FirstOrDefault()
select new
{
ParagraphNode = p,
Style = style,
};

This can look a bit strange to some upon first glance, but sometimes I prefer this style.  You just read them like queries.  This is just a matter of personal preference.
